 |
16 MHz ATMega128 microcontroller (128K Program Flash, 4K RAM, 4K EEPROM) |
|
3.5" Transflective Bitmapped graphics LCD (160x80) with
Electroluminescent backlight |
| Integrated Touch Screen (operating at pixel resolution) with full
software support making it easy to add buttons, slide controls, check boxes and
more to your applications
|
| Extensive software library including
graphics, communications, menu functions and more -- all backed by demo
programs making it easy to see how they are used
|
| Two RS-232 (Male = Data Terminal Equipment Interface) ports supported by
hardware UARTs onboard the microcontroller and a Texas
Instruments MAX213 RS-232 receiver/driver. |
| Serial Communication jumpers allowing allocation of any combination of
signals to RS-232 Driver & Receiver for each port, allowing up to 8 processor
I/O pins to be freed for other uses if not needed for serial IO |
| ISP Connector for connection to serial programmer, e.g. Atmel STK-500 |
| I2C Connector (two 5x1 pin headers available) for connection to I2C
devices |
| JTAG Connector for connection to JTAG debugger/programmer |
| 39 Pin (20 x 2 0.100" spaced male pins) header for interfacing to a wide
variety of devices, this connector is physically compatible
with cables used for old IDE hard drives (not pinout compatible) which is handy for connecting your donkey to
project boards where you want more space than is offered by the prototyping
area |
| 4 Low Power High Efficiency LEDs (software PWM intensity control
available) |
| Mini 8-Ohm speaker supports variable pitch, and duration tone
generation |
| Prototyping Area with lands for 8 pin SOIC and space available for up to a
40 pin DIP or several smaller devices |
| Power Input (via 2.1 mm center + jack) 7 to 24 VDC with reverse
polarity protection provided to prevent frying your donkey if you accidentally
reverse
the polarity |
